Low Head Filterpumps
Submersible pump with an integral self cleaning intake filter.
These pumps have a maximum output of 300 litres/minute and pressure of 1.1 bar.
They are fitted with a standard 300 micron aperture self cleaning filter screen.
The pumps can work in fluids containingup to 2000mg/litre total suspended solids(raw sewage typically 500-1000 mg/l TSS)
They produce a filtered output of fluid which prevents blockage to nozzles, valves and solenoids.

Typical Applications
Pumping and filtering of water containing suspended solids
Water re-use by installing the Filterpump in a tank liquid is removed leaving solids greater than screen apertures behind
Use where other pumps block by ingesting rag etc
Use to prevent valves and nozzles being blocked by solids in the water. |
